In scientific and market environments humidity sensors are highly appreciated devices as part of their control or monitoring systems as they allow premise operators and scientists make sure that they are operating with chemical compounds or other kind of elements in an environment that complies with the adequate levels of humidity.
There are a wide whole of applications where humidity sensors come to be useful. Humidity can have a serious impact on chemical and market processes, ruining hours and hours on end of yield and scientific efforts and this is why these instruments are so valuable.

Humidity is the article of water vapor in air and we are quite used to studying about it every morning as we listen to the weather forecast before going to work. Just as an excess of humidity makes it difficult to keep our hair level and we suffer from frizz (curly haired men and women know what I am talking about), in laboratories and market environments such as pet and human food industries, leather industries, coffee bean milling industries and beer manufacturing an excess of humidity can be absolutely serious. And just as we cannot tell exactly how wet it is face just by popping our heads out of the window, premise operators and scientists need to rely on humidity sensors or hygrometers to know if the place where they are manufacturing medicines, beer, potato chips, grind coffee, pet food, breakfast cereals and so on is dry enough. Hygrometers are highly sensitive devices that can tell quite accurately if there is a need to do some kind of adjustment to the humidity levels.
Industries and laboratories usually have more than one humidity sensor installed in their premises as each step of the manufacturing process may want accurate levels of moisture. At positive stages of the manufacturing policy a sample is taken and weighed. Then it is introduced in the moisture sensor where it is dried up. This can take several minutes or a combine of hours depending on the size of the sample and what has to be measured. Once dried, the sample is weighed again. An operator compares the two weights in order to know the water article in the introductory sample. If the succeed obtained is within accepted levels, the process continues but, if any kind of improvement or adjustment has to be made, he does it immediately so that the manufacturing process is not altered.
